About hc-27

Information about the hc-27 data set.


This dataset contains medial entorhinal cortex extracellular field potentials from six rats, each recorded by a custom electrode array made with nichrome wire stereotrodes and tetrodes, positioned at regular intervals along the dorsoventral axis of the MEC. Rats completed laps on a circle track for food rewards. Recordings were performed using a 32-channel headstage (Intan Technologies part RHD2132) connected directly to a USB interface board (Intan Technologies part an RHD2000). Raw histological micrographs of the electrode locations for each rat are detailed in MEC-TW_authorProof.pdf (linked to at the bottom of this page) supplementary figure 1.
